  They have to sign that string using salt to create hash value and pass that to onCompletion
  In the map you have to check for three keys to generate hash.
  1. hashString
  2. hashName
  3. postSalt
  
  At the end of that hashString append your salt and use SHA-512 algo on that final string to generate hash.
  Note: If you got postSalt also in the map, first use hash string append salt and then append postSalt value to that string and use SHA-512 algo on that final string to generate hash.
  Once the hash is generated use hashGenerationListener parameter to pass the hash to SDK. Example code:
